Tepco plans to pump up groundwater and discharge it to the sea
200 ~ 400 m3 of groundwater flows into the basement floors of reactor 1 ~ 4 on the daily basis.
Tepco still injects 600m3 of water to reactor 1 ~3 everyday, contaminated water increases by 800 ~ 1000 m3 everyday. Currently, 98,000 m3 of contaminated water is under reactor 1 ~ 4.
To reduce groundwater to flow into the basement floors by half, Tepco is going to make 14 wells (30cm diameter, 32m deep) at 80 ~ 200 m far from the plants on the mountain side. The pumped up water will be discharged to the sea directly, but they measured tritium from one of the three wells which Tepco made experimentally. METI states they want to ask local governments and Fisheries Cooperative Association for agreement to discharge the contaminated water.
This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
